Centre for new antibacterial strategies (CANS) is a large interdisciplinary centre at UiT – The Arctic University of Norway for research, education, innovation and dissemination related to antimicrobial resistance (AMR). CANS currently involves sixteen research groups located at three faculties and covers topics within marine bioprospecting – identification and characterization of new antibacterial activities, design and synthesis of new antibiotics and resistance inhibitors, the evolution and molecular epidemiology of AMR, host-microbe-drug interactions, and antibiotic stewardship.
The centre aims to strengthen current activities, but also support new basic research in novel concepts for sustainable antibacterial activities in AMR-prevention and treatment strategies through new permanent and temporary (tenure-track, postdoc and PhD) positions.

Presentation by Professor Thomas Rades, Research Chair in Pharmaceutical Design and Drug Delivery at the Department of Pharmacy, University of Copenhagen, Denmark.
In the context of pharmaceutical development poor aqueous solubility remains a challenge for most low molecular weight drugs. Despite the availability of a range of solubility enhancing strategies, especially for the so-called “brick dust molecules” enabling formulations are increasingly required.
In this context also amorphous forms of drugs are used. Whilst it can be stated that today amorphous solid dispersions are an advanced routine formulation approach, a better understanding of the amorphous forms of the drug molecules themselves remains an issue of important research, both as a rational basis for the development of ASDs as well as for the exciting opportunity to enable the development of amorphous engineering approaches.
In this presentation we will discuss several case studies of our own work on amorphous form diversity, ranging from preparation dependency of amorphous characteristics to the preparation and investigation of polyamorphous forms of drugs.

On-Chip Synthesis and Evaluation of Targeted Nanomedicines
Where: Aud 4, MH-building – Tromsø
When: Mai 15. 2025 at 10:50 – 11:25
Presentation by Assistant Professor Hagar Labouta, a Keenan Professor of Medical Discovery at Unity health Toronto and Assistant Professor at the University of Toronto at Leslie Dan Faculty of Pharmacy and Institute of Biomedical Engineering.
Microfluidic organ-on-a-chip models are advancing drug delivery by enabling biologically relevant platforms for evaluating therapies in complex pathophysiological systems. This talk will focus on the work done by the Labouta lab to develop innovative models that replicate critical interfaces and conditions, such as the placenta-on-a-chip, designed to study maternal-fetal nanoparticle transport and targeted delivery.
Beyond pregnancy, I will also present recent findings on our vessel-on-a-chip model for studying endothelial responses to shear stress and genomic instability, shedding light on vascular drug delivery and related pathologies. These models are complemented by microfluidic synthesis platforms that enable precise control over nanoparticle size, surface properties, and loading eDiciency.
Together, these technologies provide an integrated framework to optimize drug delivery systems and accelerate their translation to address complex medical challenges.

Discovery of Antibiotic Resistance in Newly Identified Bacterium

In 2020, a research group at UiT The Arctic University of Norway in Tromsø discovered a previously unknown bacterium. You may have heard of Staphylococcus aureus (golden staph), but this one belongs to the white variety.
The newcomer, discovered in Tromsø in Northern Norway, was proudly named Staphylococcus borealis (S. borealis) after the Northern Lights.
But how dangerous is it really, and is it a threat to us at all?
33 Percent Antibiotic Resistance
To investigate, researchers collected bacterial samples stored in freezers at several Norwegian hospitals.
The samples went as far back as 2014, and the researchers conducted new tests to see if they could identify the new bacterium in the old samples. Meanwhile, new samples arriving at the UiT lab from 2020 to 2024 were tested continuously. In total, the researchers collected and analysed 129 samples from seven Norwegian hospitals.
It turns out that S. borealis is resistant to more than three different classes of antibiotics in one-third of the cases where it was tested.
"We see the most resistance against the antibiotic classes fusidic acid, cephalosporins, penicillins, macrolides, and fluoroquinolones," explains Jorunn Pauline Cavanagh, who led the work on bacterial analyses.
Moreover, the bacterium also appears to be highly adept at acquiring protective mechanisms from other bacterial species. This means it could potentially develop antibiotic resistance quickly, when attacked with the medicines currently available.
A Problem for the Elderly
S. borealis is a bacterium that lives on our skin, and researchers have found that it can become problematic when your immune system is weakened. This makes it particularly concerning for the elderly and for those who have had knee or hip replacements.
"This bacterium is an opportunist that can cause illness when your immune system is compromised. For example, we see that it can form what’s called biofilm around knee prostheses and cause infections that can be difficult to treat," explains Jorunn Pauline Cavanagh.
Researchers are now working to determine which diseases this bacterium can cause. Preliminary findings suggest it may lead to urinary tract infections, as well as inflammation in areas where implants are present.
"We do know that it causes mastitis in dromedary camels. This is because we’ve published the bacterium’s genetic profile in international databases, which other researchers use to compare their own bacterial findings. So, more possibilities may emerge," says Cavanagh.

This bacterium outsmarts our defences, but we are on its heals
POPULAR SCIENCE: Meet Staphylococcus aureus, the ultimate microscopic escape artist that invades, adapts, tricks, and thrives within our bodies.

As part of the larger global crisis of antimicrobial resistance (AMR), the bacterium Staphylococcus aureus represents a formidable challenge.
You might have heard about MRSA? This is the version that is resistant to the antibiotic Methicillin, and it is pushing modern medicine to its limits.
Infections with Staphylococcus aureus range from mild skin irritations to serious life-threatening diseases like pneumonia and bloodstream infections. This places it at center stage of the ongoing battle between microbes and medicine.
The invisible battle inside your body
Whether it’s dodging your immune system’s attacks or hijacking your cells’ energy, this microbe has evolved survival strategies that challenge our immune system and even our best antibiotics. The result is a brutal match between two hardcore players chasing each other inside your body.
On one side of this war is Staphylococcus aureus. On the other side is your strong immune system, constantly defending you.
But how does this tiny invader manage to outsmart such a powerful defence network as our immune system?
